1583 // * changed stored pref representation as before.
1584 // the array of objects is 1) bigger and 2)
1585 // less portable. If we would import packed pref
1586 // objects and the object definition was changed, PHP would fail.

1604 // your logo and signature image files "YourWikiNameLogo.png" and
1605 // "YourWikiNameSignature.png" and put them all into
1606 // themes/default/images. YourWikiName should match what is defined as
1607 // WIKI_NAME in index.php. In case the image is not found, the default
1608 // shipped with PhpWiki will be used.

1611 // Inconsequential decrufting.
1613 // Revision 1.67 2003/02/26 03:40:22 dairiki
1614 // New action=create. Essentially the same as action=edit, except that if the
1615 // page already exists, it falls back to action=browse.
1617 // This is for use in the "question mark" links for unknown wiki words
1618 // to avoid problems and confusion when following links from stale pages.
1619 // (If the "unknown page" has been created in the interim, the user probably
1620 // wants to view the page before editing it.)

1637 // New WikiLink type 'if_known'. This gives linkified name if page
1638 // exists, otherwise, just plain text.
1640 // Revision 1.61 2003/02/18 21:52:05 dairiki
1641 // Fix so that one can still link to wiki pages with # in their names.
1642 // (This was made difficult by the introduction of named tags, since
1643 // '[Page #1]' is now a link to anchor '1' in page 'Page'.
1645 // Now the ~ escape for page names should work: [Page ~#1].
